Set in the 25th century, the story of THX 1138 takes place entirely inside a vast, technologically advanced civilization constructed under the Earth’s surface. This gleaming white dystopia is chock-full of a population of humans who are forced by their government to shave their heads, wear all white clothes and consume a daily regimen of sedative capsules to keep them in line. Mindless production and consumption are the norm, while sex, love and emotion are forbidden.
